Tech Oversight Project — Headquarters: Washington, DC

Note: The source text explicitly mentions 'Washington, D.C.' in the context of describing where the organization shapes the debate around tech policy. While the source does not explicitly state 'Headquarters = Washington, DC' in a single sentence, the organization's focus on 'tech policy in Washington, D.C.' combined with the About Us page context strongly indicates Washington, DC as the operational base. The claim is confirmed by the source material.

Note: The source text explicitly states the organization's mailing address as 'PO Box 3010 Washington, DC 20010' in the footer section. Additionally, the text describes the Tech Oversight Project as 'the only tech watchdog dedicated solely to research, rapid response, and aggressive media tactics that shape the debate around tech policy in Washington, D.C., and statehouses across the country,' which further confirms Washington, DC as their location of operations. The claim that their headquarters is in Washington, DC is directly confirmed by the source.
